ABSTRACT:
A sintering plant of the type sintering raw materials, such as pulverized ores, while transporting them with a conveyor, in which quicklime is fed to the lower layer of the raw materials on the conveyor so that SO.sub.x produced during sintering process may be mainly contained in gases discharged to the downstream half of wind box array disposed below the conveyor and the gases only from the downstream half are fed through a heat exchanger to a desulfurization equipment having a relatively low capacity. The heat exchanger is arranged to heat water to be fed to a device, such as waste heat boiler, adapted to be operated with thermal energy recovered from a cooler for cooling the finished sinter discharged from the conveyor, whereby the thermal efficiency of the plant can be much improved.
